This grant aims to drive research that will shape the future regulatory framework for a Digital European Sky (DES). The core objective is to address the impact of automation and Artificial Intelligence (AI) on human roles, enhance Air Traffic Management (ATM) safety, harmonize airspace classifications, and integrate environmental considerations within the aviation sector. Target recipients include organizations involved in aviation research, technology development, air traffic service providers (ATSPs), air navigation service providers (ANSPs), and manufacturers. This is a SECTOR-SPECIFIC grant focused on civil aviation and related technologies. The geographic scope includes European countries, and potentially other non-EU/non-Associated countries with specific funding arrangements. Key filtering criteria for initial screening are a strong focus on aviation, ATM, AI, human factors, and regulatory research in the context of safety and environmental impact. This grant is part of the ongoing SESAR 3 Joint Undertaking Bi-Annual Work Programme, indicating a recurring program context.
